Nanotechnology and Targeted Drug Delivery to the Brain
Nanotechnology is revolutionizing targeted drug delivery by overcoming the challenges posed by the blood–brain barrier. Engineered nanoparticles, liposomes, dendrimers, and polymer-based carriers enable controlled release and site-specific targeting of therapeutic agents. These technologies improve bioavailability, reduce systemic toxicity, and enhance treatment precision for neurological disorders. Functionalized nanocarriers can be designed to respond to specific molecular signals within diseased brain regions. Integration with imaging modalities supports theranostic applications, combining diagnosis and therapy in a single platform. Ongoing research emphasizes safety evaluation, long-term stability, and scalable production methods. Nanomedicine represents a transformative approach to delivering next-generation neurotherapeutics effectively and safely.
